Spectatio 是一个开源测试框架，用于在真实设备和虚拟设备上测试 Android Automotive OS (AAOS)。Spectatio 提供用于在汽车设备上测试应用的 API，它是一种可扩展、可伸缩的解决方案，用于验证 AAOS 及其应用的功能和性能。
概要设计
Spectatio 框架可适应各种 AAOS 界面实现，并相应地扩展。该框架用于在设备硬件、模拟器和虚拟环境中测试 AAOS 的功能和性能。
下图说明了 Spectatio 框架的概要设计。
图 1. Spectatio 框架概要设计
Spectatio 框架基于 UI Automator 构建，该框架提供了一组 API，这些 API 可用于构建与 AAOS 用户和系统应用交互的界面测试。Automotive 测试使用 Spectatio 框架提供的 API 进行测试，所以这些测试独立于受测设备 (DUT)，并且可扩展为测试各种设备（如果支持）。
图 1 显示 Spectatio 框架基于拨号器、Medicenter 和“设置”等参考应用实现了模块化，并使用应用专用的接口和辅助程序，使其能够针对新应用轻松扩展。Spectatio 框架会重复利用通用标准和实用程序辅助类。标准辅助类是所有应用辅助函数的父类，它提供设备专用或适用于各种应用的标准函数。实用程序辅助类提供了各种实用程序，例如从设备读取或写入文件的实用程序。
架构
为了提供一组 API 来构建界面测试，Spectatio 框架实现了应用专用的界面和辅助程序，同时扩展现有的标准辅助类，并导入实用程序辅助类。
下图说明了 Spectatio 框架的概要架构，以及为应用测试实现 API 时所涉及的所有实体。
图 2. Spectatio 框架概要架构
应用辅助接口提供了实现应用辅助程序的蓝图。它包含测试应用所需的各种辅助函数。每个应用都有自己的接口，例如 IAutoSettingHelper 和 IAutoDialHelper。如需了解详情及查看接口函数列表，请参阅 AOSP 上的应用辅助接口函数。
标准辅助类包含设备设置所需的标准属性和函数（但不特定于任何应用，例如 pressHome 和 scroll）。标准辅助类需在 AbstractAutoStandardAppHelper.java 中定义。
Spectatio 框架会使用实用工具辅助类。例如，AutoJsonUtility.java 是一个
实用程序类，用于加载给定的设备 JSON 配置文件并在运行时更新框架配置。
应用辅助程序实现模块是 Spectatio 框架的核心。该模块包含应用辅助接口中所定义辅助函数的实现，而相应辅助函数是在汽车设备上测试应用所必需的函数。每个应用都有自己的实现（如 SettingHelperImpl 和 DialHelperImpl），Automotive 测试会利用这些实现来测试应用。如需了解详情和实现列表，请参阅 AOSP 上的应用辅助程序实现函数。
Automotive 测试使用应用辅助程序实现函数来测试与应用相关的各种操作。使用 HelperAccessor 类获取对应用帮助程序实现函数的访问权限。
以下代码显示了一个汽车测试示例的设置、清理和执行过程。
@RunWith(AndroidJUnit4.class)
public class AutoApplicationTest {
static HelperAccessor<IAutoApplicationHelper> autoApplicationHelper =
new HelperAccessor<>(IAutoApplicationHelper.class);
public AutoApplicationTest() {
// constructor
// Initialize any attributes that are required for the test execution
}
@Before
public void beforeTest() {
// Initial setup before each test
// For example - open the application
autoApplicationHelper.open();
}
@After
public void afterTest() {
// Cleanup after each test.
// For example - exit the application
autoApplicationHelper.exit();
}
@Test
public void testApplicationFeature() {
// Test
// For example - Test if application is open
assertTrue("Application is not open.", autoApplicationHelper.isOpen());
}
}
自定义
Spectatio 框架独立于设备界面，因此具有可伸缩性，便于测试具有不同界面和硬件的设备。为了实现这种可伸缩性，Spectatio 使用基于参考设备的默认设备配置。
为支持非默认的设备配置，该框架在运行时会使用 JSON 配置文件为设备设置所需的界面更改。JSON 配置文件支持 TEXT、DESCRIPTION 和 RESOURCE_ID 等界面元素以及 path 设置，并且只能包含有关 DUT 的界面更改的信息。其余界面元素会使用该框架中提供的默认配置值。
默认设备配置
下方的 JSON 配置文件示例显示了可用的设备配置及其默认值。

非默认设备配置
下方的代码是 JSON 配置文件的示例，其中默认设置已由 DUT 上的设置替换。在此示例中：
- 互联网设置在参考设备上被命名为
Network & internet，在 DUT 上被命名为Connectivity。 - 对于参考设备，可在
Settings > Date and time中使用日期和时间设置；对于 DUT，可在Settings > System > Date and time中使用日期和时间设置。
# JSON configuration file for Reference Device
{
....
"NETWORK_AND_INTERNET_SETTINGS": {
"path": "Settings > Network & internet"
},
"DATE_AND_TIME_SETTINGS": {
"path": "Settings > Date and time"
},
....
}
# JSON configuration file for non-reference device
{
....
"NETWORK_AND_INTERNET_SETTINGS": {
"path": "Settings > Connectivity"
},
"DATE_AND_TIME_SETTINGS": {
"path": "Settings > System > Date and time"
},
....
}
当 JSON 配置文件准备就绪后，系统会在运行时提供该文件，如以下代码块所示。
# Push The JSON configuration file to the device
adb -s DEVICE-SERIAL push PATH-OF-JSON-FILE /data/local/tmp/jsonFile.json
在以下命令中：
- PATH-TO-JSON-FILE：宿主机上的 JSON 文件路径。
- DEVICE-SERIAL：DUT 的序列号。如果只有一台设备连接到主机，则无需使用此参数。
构建与执行
Spectatio 框架会自动构建为测试 APK 的一部分。如需构建测试 APK，AOSP 代码库必须位于本地工作站上。构建测试 APK 后，用户必须在设备上安装 APK，然后执行测试。
以下代码示例展示了测试 APK 的构建、安装和执行过程。
# Build Test APK
make TEST-APK-NAME
# Install Test APK
adb -s DEVICE-SERIAL install -r PATH-FOR-BUILT-TEST-APK
# Execute Test with the JSON file
adb -s DEVICE-SERIAL shell am instrument -w -r -e debug false -e config-file-path /data/local/tmp/jsonFile.json -e class TEST-PACKAGE.TEST-CLASSNAME TEST-PACKAGE/androidx.test.runner.AndroidJUnitRunner
在以下命令中：
TEST-APK-NAME：待测试应用的名称。例如，将 TEST-APK-NAME 设置为
AndroidAutomotiveSettingsTests便可测试Android.bp文件中指定的 Wi-Fi 设置。您可以在 Automotive 测试对应的Android.bp文件中找到 APK 的名称。DEVICE-SERIAL：DUT 的序列号。如果只有一台设备连接到主机，则无需使用此参数。
config-file-path：可选参数，只有在按 JSON 配置文件中指定的方式提供非默认设备界面配置时才需要使用。 如果未提供该参数，则 Spectatio 框架会使用默认值来执行测试。PATH-FOR-BUILT-TEST-APK：系统在执行
make命令时构建测试 APK 的路径。TEST-PACKAGE：测试软件包的名称。
TEST-CLASSNAME：测试类的名称。例如，对于 Wi-Fi 设置测试，测试软件包的名称为
android.platform.tests，测试类的名称为WifiSettingTest。
